摘要： Provided is an objective optical system employing a gradient index (GRIN) lens. A refractive index of the GRIN lens is changed in an axial direction and a direction perpendicular to the axial direction. The GRIN lens has a refractive index n satisfying the following equation: n ⁡ ( r , z ) = ∑ i = 0 ⁢ ⁢ n r2i ⁢ r 2 ⁢ i + ∑ j = 0 ⁢ ⁢ n zj ⁢ z j where z is a distance from the center of the lens in the axial direction and r is a distance from the center of the lens in the direction perpendicular to the axial direction. Thus, an objective optical system with a high numerical aperture can correct aberration.
